Question

Hello,Here is a point that I am having difficulty to relate with one of the equations. Thanks.

Answer 1

Case: Lines

Method:

Here we look at the lines by testing them on the points

A)

x - y - 6 = 0

(5, -1)

5 - (-1) - 6 = 0

5 + 1 - 6 = 0

6 - 6 = 0 (True)

B)

x + y + 6 = 0

(5, -1)

5 + (-1) + 6 = 0

5 - 1 + 6 = 0

10 is not equal to 0

(False)

C)

x + 5y -6 = 0

(5, -1)

5 +5(-1) - 6 = 0

5 -5 -6 = 0

- 6 is not equal to 0

(False)

D)

x + 5y + 10 = 0

(5, -1)

5 + 5(-1) +10 = 0

5 - 5 +10 = 0

10 is not equa; to zero

(False)

Final answer: Option A

x - y - 6 = 0
